Abstract (en)
[origin: EP0597196A1] The invention relates to a seed drill (1) having a cam-type sowing wheel (15) which can be used both as a fine-sowing wheel and as a normal-sowing wheel. It is used on the one hand with top discharge and on the other hand with bottom discharge, along with an alternating direction of rotation. Between the two sectors of use there remains an interval in which seed conveyance is not possible, because the rotational speed cannot be reduced as desired in the bottom discharge and cannot be increased as desired in the top discharge. So as also to cover this sector, there is provided a pivotable cover (16) which not only ensures in the top discharge, by means of stripping tongues (162), that only one seed grain per cam is conveyed at a time, and, in the bottom discharge, allows the conveyance of the seed located between the individual cam-type wheels (15), but furthermore can be brought into a position in which these interspaces are made ineffective for conveyance. <IMAGE>
